VI. F. 加倍弱2开叫后的lebensohl 起初没有理解strain一词的意思,把直接跳3NT和先2NT再3NT的意义搞反了。 strain: one of the four suits or notrump; the non-numerical element of a bid; denomination. -- from glossary of www.bridgeworld.com 疑问:这里和1NT被争叫后的lebensohl不一样? 但先2NT再扣叫问高花又是表示有止张,2NT的意义似乎不太统一。 直接跳3S和先2NT再3S的意义也和我以前的理解颠倒。
优先解释: 当一个叫品有多个可能的解释,且没有明确的体系约定,那么则应该被考虑为: (a) 自然而不是人工叫品; (b) if a double, non-penalty or penalty by which seems more sensible to the observer ; (c) lead-directing or not by which seems more sensible to the observer; (d) if a redouble, business or escape by which seems more sensible to the observer; (e) if a pass over an opponent’s redouble, penalty or escape by which seems more sensible to the observer. --------------------------------------------------------------------- 翻译: (a) 自然而不是人工叫品; (b) X,由旁观者的角度看起来,更象是非惩罚或惩罚; (c) 由旁观者的角度看起来,更象是指示攻牌或不是; (d) XX,由旁观者的角度看起来,更象是想打或逃跑; (e) 在OPP XX后的Pass,由旁观者的角度看起来,更象是想打或逃跑; ----------------------------------------------------------------------- 跳叫: 比splinter高一阶的跳叫(如1S-5D)的缺省含义是排除性关键张问叫(该原则有明确的例外)。
示攻性加倍: (a) 对没有实叫花色而叫到的3NT或4NT的加倍,要求首攻人攻自己较短的高花。 (b) 下列加倍不指示首攻 (1) 对没有实叫花色而叫到的6NT或7NT的加倍; (2) when some combination of dummy’s suit, leader’s suit, and doubler’s suit is available; (3) when there are expected and unexpected leads; or (4) after the opponents’ previously uncontested Stayman auction. (c) 对花色定约的不寻常收攻加倍取消先前作出的首攻指示。
2NT: Competitive two-notrump bids that might be used artificially to help distinguish actions designed to contest the auction from those of a constructive nature are natural.
??1/1花色应叫、开叫人跳再叫2NT后: (a) 再应叫3C是人工的,要求开叫人叫3D,除非对应叫高花有3张支持(接着,应叫人在3阶原花色及以下的叫品都不逼叫; otherwise, responder’s next bid is a signoff if that is possible; otherwise, it is a choice of games if that is possible; otherwise, it is a checkback for an eight-card major-suit fit if possible; otherwise, it converts the three-club rebid into a natural bid in the minor three diamonds over two notrump would not have shown); (b) 再应叫3D显示配合开叫的低花。
4. 信号含义(何时发送哪种消息) (A) 当跟出同伴的攻牌: 态度(不欢迎信号暗示能够支持明显的转攻),但 (1) 当攻出大牌而明手单张将能够将吃时,花色示选; (2) count at trick one when not beating dummy’s card or finessing and dummy’s highest is the jack or lower or the equivalent (B) 当跟从庄家或明手的出牌: 张数 (C) 将牌花色: 张数;但当有很清晰的防守路线时,花色示选 (D) 垫牌: (1) 从有赢墩能力的连张或内嵌连张中:等值最大 (2) 一个花色中的首次垫牌:态度 (3) 一个花色中的第二次垫牌:张数 (4) 和其他花色相关的垫牌:花色示选 (E) 当第二家分出大牌时:AK出K;此外,等值最大 (F) 贯穿防守: (1) 优先打张数信号的特殊情况: 有将满贯定约的第一墩;攻K以后 (2) 通常:不寻常的打牌显示不寻常的持牌情况,或要求同伴不寻常地打牌
